You don’t have to follow enterprise IT too closely before you become familiar with the idea of SD-WAN. It’s the chili of enterprise networking. Everyone seems to have their own recipe, but when you look in the pot, they all look similar. Some come canned from a company, making it easy to deploy into a bowl. Others provide a few secret spices to add to what you’re already cooking. And some organizations just roll their own from scratch. There’s great debate whether IWAN is chili, or simply a very complicated stew. In the SD-WAN chili cook-off, TELoIP might not have the biggest booth at the fair, but they’ve got a pretty unique recipe to test your palate.
After reading this post about the inherent problems of TCP connection termination, I almost feel sorry for the protocol. It seems to be trying so hard, but doomed for inevitable failure. Martin Sustrik goes through all the reasons this is problematic in great detail.
In this edition of Gestalt Networking News:
– IPv6 has a case of the Mondays
– Do network engineers need to be programmers now?
– Plus, the epoch rollover struggle is real
Does a network engineer need to now do software development? Is that the direction the industry is going? Jason Edelman weighs in.
Extreme Networks buys Brocade’s data center networking, Bedrock Data expands its Board of Directors, E-Discovery is a problem in IT, and Alliance Storage Technologies updates NETArchive.
Water planes, trains, and automobiles, that’s the fantasy allegorical landscape consuming this post by Ivan Pepelnjak. He paints a landscape where trains have consumed all transportation, to the point that there are no roads, only rails, and on it run electric trains. Cars do exist in this realm, but run on the rails, and are beholden to the train vendors for their efficient electric engines. But now the landscape is changing. New cheap gravel roads allows for inefficient gas cars to run at dirt cheap, and travel places the trains can’t. Ivan wants to know how the train manufacturers will do?
Dan Goodin at Ars Technica gives an overview of the implications of the recently exposed telnet vulnerability disclosed by WikiLeaks. I’m not surprised the CIA had something like that, however morally dubious I may find it. As an intelligence organization it’s in their interest to have this kind of access. For me, this goes beyond Cisco.
Chris Marget wrote up a nice piece looking into a similar bug. It’s probably not going to by as hyped as Y2K, but it’s nonetheless important. Because of the 32-bit signed integer used in Unix-based systems, there’s a maximum value of 2.1 billion seconds in the “epoch”, before it basically runs out and started back over at the beginning with 10000000000000000000000000000000. That may sound like a lot, but it’s actually about 68 years. Since the Unix epoch begins on January 1, 1970, this means we’re due for an epoch reset around 2038.
The Internet of Things in a technological hypebeast, being both clearly defined and a marketing ploy at the same time. Cisco has clearly defined what they think IoT is all about: adding connectivity to devices. Using LoRaWAN, Cisco has a compelling technical solution to making connectivity possible on a mass scale.
